Mildew-prevention medicament for wool storage and preparation method thereof

Abstract

A mildew-prevention medicament for wool storage and a preparation method thereof are disclosed. The mildew-prevention medicament for wool storage comprises a shell and a medicine. The shell is prepared from the following raw materials (by weight): 40-50 parts of starch, 20-30 parts of bentonite, 10-20 parts of talcum powder and 25-35 parts of water. The medicine is prepared from the following raw materials (by weight): 10-20 parts of nicotine, 10-20 parts of sulfonic acid, 5-8 parts of dimethyl formamide, 20-30 parts of carbon disulfide and 40-60 parts of ethanol. The preparation method comprises the following steps: fully mixing the shell materials, namely starch, bentonite, talcum powder and water, heating to 70-90 DEG C, cooling to prepare an empty-shell pill, and drying in the sun; fully mixing nicotine, chloropicrin, carbon disulfide and ethanol, injecting the medicine mixture into the dried empty-shell pill, sealing the pinhole formed by the injection with starch so as to form a sealed pill; and vacuum-packaging the pill. The medicament of the invention has a good insect-expelling effect, has good drug effect, will be thoroughly evaporated, and will not cause secondary pollution.

Description

[0001] Technical field: [0002] The invention relates to the technical field of anti-mildew drug production, in particular to a drug for preventing mildew in wool storage and a preparation method thereof. [0003] Background technique: [0004] In the prior art, wool tends to absorb moisture during storage, thus becoming moldy and infested with insects. In order to prevent mildew and infested wool during storage, sprays or fumigants are often used as anti-mildew agents. Chemicals, and sprays will affect the texture of wool and are more polluting. They are used to kill insects or prevent mold growth, and fumigants are generally divided into solid fumigants, liquid fumigants and gas fumigants, which are generally used in wool storage. Solid fumigants, but the evaporation of solid fumigants is not obvious, there are fewer types, the anti-mildew effect is poor, the evaporation is not thorough enough, and the residue is easy to cause secondary pollution.
